replica de Forest oscillion transmitter

This session we build a replica of one of de Forest's very first vacuum tube transmitters. He had made many arc transmitters but they were very inefficient and unreliable. He then built a much more powerful audion vacuum tube he called an "oscillion." This had a much larger filament and plate so it could handle significantly more power than the spherical audions which were used for receiving sets. We will now build a replica of one of his very first vacuum tube radio telephone transmitters! He built this model sometime between 1915 and 1920.

OH my. Please get a push stick for your table saw. I love this channel. You're amazing.

Watching a genius at work. What a treat. Thank you, Ron. God bless you and God bless America. 🇺🇸

[@goldenboy5500]

your knowledge of old radio is next to none I enjoy every video you produce I have learned so much with your work your an amazing teacher

[@Niek2154]

The first radio broadcast in the Netherlands was provided by Hanso Idzerda with a Forest Oscillion transmitter, That was on November 6, 1919. Very nice that you made one.

[@paulkocyla1343]

Damn, that´s a thing of beauty! Very very nice build!

[@TheGuitologist]

This is an absolute work of art. It is like time travel. We are witnessing the dawn of an age as it must have looked over 100 years ago. I am in awe.

[@zx8401ztv]

What an amazing replica you have created, and it works far better than i would have thought :-D Ron you have no idea how amazing you are, and you make it look so easy, but it's not.

@meraydin1 Yes I agree. Ron could sure use some table saw push sticks to keep those fingers safe. There are plenty of free templates for them on the internet.

We need a tube transmitter that hasn’t been made in 100 years, Glasslinger: hold my beer.

[@JerryEricsson]

Back when I was a boy in the early 1960's my best friend and I used to make raids on the town dump grounds. We were both from very poor families, and got by on a dollar a week allowance, so if we wanted stuff to tear apart, the town dump was a wonderful supply. There were no guards, or "attendants" as there are today, just a huge pit where the city garbage truck (driven by my Uncle Clarence) would dump the town's garbage daily. We always found wondrous things, my friend liked to tear apart stuff for the copper which he sold to the local junk yard, myself, I liked parts for radios and the like. I once found the front of an old radio receiver much like the one you had in today's video. I knew it was from an early radio, all the variable capacitors and rheostats were there but the rest of the radio was gone. Oh I found other great items, the only thing I have left from those days were a set of butcher knives that I found right after one of the local slaughter houses went out of business.

[@madflamingo]

You are by far my favorite KZbinr. What I admire most is your positive attitude and your ability to laugh at yourself while being so passionate about these things. I learn a lot about the electronics, but most of all, I learn how I want to live my life, creative and positive. Thank you so much for these. You remind me of my great grandmother who passed long ago, but who was always positive and whom I loved dearly. Thank you again.

[@hectorpascal]

Ron, you are undoubtedly a genuine "National Treasure"!

[@WhoFlungPoo2024]

This is a master class in ingenuity and craftsmanship. It was a pleasure to watch.

[@Iconoclasher]

It's amazing! 😊 DeForest was kinda flying in the dark when he invented this transmitter. He not only had to make a coil, he had to know a coil was required and where to place it in the circuit. Same with the vacuum tube. I suspect he found a thousand ways how not to make a transmitter before he stumbled on this design that worked.

[@hestheMaster]

Skilled at carpentry and early electronics. Absolutely superb Ron!😎

[@AtlasReburdened]

What an outstanding replica. Thanks for sharing, Ron.

[@salat]

I simply love your videos, especially because you display - hand (re-)building of good aged technology - the beautiful art of restoration - your calm teaching voice - cat content

[@RapperBC]

xraytonyb sent me here, and boy howdy do I not regret droping in again. That was a pretty amazing display of skills and knowledge.

[@allthegearnoidea6752]

That large coil you wound is a thing of beauty. Stay safe regards Chris

[@moasias9306]

Wow !! That is fantastic, amazing and a piece of art antique. thank you so much, you brought this old technology from the past and gave it a life, really you are a creator.

[@sonofeloah]

It is said there is a fine line between genius and insanity (I prefer crazy) and my friend, you are there! None of these kids nowadays could even dream to do what you do and in a pinch of all hell breaking loose, who is going to talk to others at a distance and who is not. And an EMP will fry all of the kid's goodies and the tube sets will keep humming along. Thank you for sharing with us and giving us hope to bring back an era long forgotten.

[@brentrobeson2819]

[@ladamurni]

I like restoring tube radio's but I don't even have half the knowledge and skill you have. What you have made here is stunning, i have also seen how you made that tube that is also stunning! Thank you for the video and hope for more to come! All the best from the Netherlands.

Nice work Ron! I thought it was going to be a non working museum piece, but you made it work! On the brass plaques, you made them look like they survived in a smoke filled radio room of the 20s for a couple of decades. Thankfully, we have mostly given up smoking, except for an occasional circuit or two! Keep up the videos! I enjoy the education!

[@timseich7219]

[@MrChief101]

Utterly fascinating-- every step. One wonders what Mr. De Forest would think of this-- maybe not as surprised as one would suppose. The early experimenters were all over the place. There were a lot of amateur builders and he might recognize you as being very familiar. Perhaps not as "amateur"! Never mind his reaction to all the modern equipment-- though you have quite a bit of old stuff to make him feel right at home. Remarkable multi-disciplinary fabrication. And-- the damn thing looks great.

[@chetpomeroy1399]

[@garyramsey4275]

Outstanding work, Ron! Glad to see that your second attempt at the oscillion tube was a success. I imagine that an internal power supply probably was not part of the original; but great that your version includes an “almost” period internal supply. Love the coil slider design and construction, and the nameplates are beautiful. Best of all, it works!
